Echo: ch.qos.logback:logback-core: security update to 1.5.33

medium Tenable Cloud Security Plugin ID 457846

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Deserialization of untrusted data vulnerability in QOS.CH Sarl logback logback-core
 (HardenedObjectInputStream (logback-core) modules) allows Object Injection albeit heavily restricted. More
 precisely, an attacker able to influence serialized data sent to SimpleSocketServer or
 SimpleSSLSocketServer can instantiate objects from classes in the java.lang and java.util packages that
 are not explicitly blocked. Although deserialization is heavily restricted by HardenedObjectInputStream
 and no practical way to achieve remote code execution or significant privilege escalation has been
 identified, this issue constitutes a bypass of the intended security restrictions. This issue affects
 logback: through 1.5.32 inclusive. (CVE-2026-9828)

Solution

Update the ch.qos.logback:logback-core library and its related packages to version 1.5.33 or later.
